METHOD AND APPARATUS FOR LAUNCHING AND RECOVERING A REMOTE INSPECTION DEVICE

The present disclosure relates to methods and apparatus for launch and recovery of a remote inspection device within a liquid storage tank. In one embodiment, the tank is accessed by opening an entrance hatch and then injecting a vapor suppression foam across a surface of a stored liquid mass to form a foam layer. A launching system having a remote inspection device is attached to the entrance hatch to define a launch and recovery space sealed from an external environment and isolated from the stored liquid mass in the tank via a valve and the foam layer. The launch and recovery space is purged of hazardous vapors by injection of an inert gas prior to launch and recovery of the remote inspection device. Prior to removal of the launching system, the surface of the stored liquid mass is re-coated with vapor suppression foam.

ENVIRONMENTALLY-CLEAN BIODEGRADABLE WATER-BASED CONCENTRATES FOR PRODUCING FIRE INHIBITING AND FIRE EXTINGUISHING LIQUIDS AND FOAMS FOR FIGHTING CLASS A AND CLASS B FIRES
20220054876 · 2022-02-24 · ·

Environmentally-clean biodegradable water-based biochemical concentrates for producing fire-inhibiting and fire-extinguishing liquids and foams for fighting Class A and/or B fires. The concentrates are formulated using generally safe food-grade chemicals, for foaming agents, surfactants and dispersants, and fire inhibiting extinguishing agents, without the use of phosphates and ammonia compounds. Automated proportioning and mixing devices and systems can be used to mix the biochemical concentrates with proportioned quantities of pressurized water so as to produce fire inhibiting and extinguishing water streams, as well as finished firefighting foam materials, to both inhibit and extinguish fire involving Class A and/or B fuels.

Integral temperature responsive fire suppressant modular interior system
20170234003 · 2017-08-17 ·

A construction material consisting of a deployment system for a tire retardant substance, suitable for use in a wide variety of applications. This invention is designed to deploy a fire retardant substance in in response to the detection of an uncontrolled fire, thus minimizing or reducing risk of death, serious injury or property damage associated with uncontrolled fires when present in a habitable structure. The invention consists of a construction material which incorporates hinged or folding door(s) or flap(s) which contain a fire retardant substance within the construction material. When an uncontrolled fire is detected, the door(s) or flap(s) open and thus deploy the fire retardant substance onto the area affected by the uncontrolled fire.
